Question

give the product of the reaction of butanedioic acid with two moles of 1-butanol.

Answer 1

I presume you mean the formation of the di-ester: di-n-butylsuccinate, also called butanedioic acid dibutyl ester.

It is unlikely these will react just by mixing, it would need a little acid for catalyst and a way to remove the water byproduct to drive the equilibrum to the products side.
